I so want to do what you did with your lights and switch. Did you ever create a diagram of the wiring? Do you know the proper name for the switch so I can search for it stateside on Amazon. Thank you for the video and any help you could provide.
Good job, it doesn’t look too bad overall and I really like what ur doing with the hot water system idea. I would suggest some sort of a balancing system for ur batteries may help them perform better and curious if this system is still going or has it taken on a number of transformations over this time (3yrs). Lifepo4 is all the go now of course and the technology is constantly changing, getting flasher and dearer too. It’s been interesting following ur journey with ur system & proud to see young Aussies havin a go mate! Cheers
There are tanks with 2 elements, generally upper and lower elements I believe, I think David Poz did a review on a dc system he was doing. So was the problem that you couldn’t produce enough solar power to heat the large tank quick enough with the 900watts it was getting in previous video? The smaller tank is probly a good quick fix, but a few more panels or a larger or second element may have maintained the bigger tanks temp better, which is handy to have the extra storage if you get a week or three of shite weather & no extra power for heating water. Cheers
Hey mate, good job, I like it, there are always other ways to do things but I think you have achieved a great result here in a relatively simple way, ur large Hot water tank is like another 5-8kw of battery power or more that would otherwise go unharnessed, its always good to come up with new ways to harness any extra energy you can in whatever form. Cheers
Good job mate. This looks ok for what you are trying to achieve, ur on the right track. Im guessing that is a voltage sensing relay that ur using to divert the load as the batteries reach near a full SOC based on a preset voltage.
Very nice wiring and component layout ( with no idea or comment on gauge used ) I do have a suggestion though. Look into automation. I use Arduinos ( esp-32s ) and “Node Red” to wirelessly meter my batteries and dynamically and automatically switch the solar input voltage off my controllers directly to a inverter that has a 24 - 75 volt input. The goal is to isolate fully charged batteries from the ridiculous micro charge / drain cycle. Another advantage everything is displayed on a web page accessible throughout your house and world wide if you would be less security minded.
I like the set up mate! How have you got it tied into the house system? If you’ve got a duel element tank then I’d use the top element on 230 and the bottom on 24v but ideally you’d want them right next to each other The other option if you have a existing PV array then you could get yourself a grid feed inverter have have it dump the excess power back to the grid Old workmate here in NZ had a similar system but with a wind turbine and he has the same issue of finding a use for the excess power Only trouble with using a cheap grid feed inverter is they tend to overload themselves and blow up when connected direct to a battery, so you’d have to divert it direct from the solar panels when the batteries are full
I heat all my water connecting to the PV array without going thru a charge controller or using batteries. That way the batteries are always full and not heating CC. I use a power point controller which looks at the pv voltage to determine when the CC isn't using all the panels power. That lets me capture more power than typical CC diversion control can do and it requires no battery for highest efficiency.
@@bernardwarr4187 Yes, there are plenty of popular videos from people who don't know what they are doing. Direct connect is EASY, that is all most look for. It is inefficient and take twice as many panels to get the same performance of a system with a WH controller board. It would not be possible to heat water with PV without a sophisticated controller board at my location. I have what an engineer would design for himself. I don't want my wife saying when am I be able to use my dishwasher. I'm a dozen years ahead of the solar world.
hi on the replay it s one postive goto water element and another positive go to positive battery? and how to setup charge controller to triger the relay to dump load
hi there wen i was on a 12 volt system i had to put big wire to help the batteries nice system there the wire for the batteries be ok for 48 volt syatem
The carby on mine is crap, will run for a use and the next time the engine surges, cuts out and plays up in general. Take the float bowl off and wriggle the valve for a second and the thing works again. My personal advice is save your money until you can afford a Honda.
Could you have came out of the bottom of your mpp controller to yr breakers for yr 12v lighting? Just curious, trying to figure it all out and the way I should do it whenever I go off grid. Good job by the way. Like to watch more of yr videos!
I'd only be guessing but if you were running lights from the load on the mppt you probably wouldn't have any power at night as I think it would only get power from the solar panels.
G'day mate, love what your doing there and at such a young age to. Well done. I am building a shipping container home in Gippsland Victoria and I am on a 12 volt system and have a wind turbine, and solar array. I am just starting to piece the equipment together now for a water heater and i have ordered a 400 watt 12 vol heating element which I will put inside a small water heater. I love this journey, it has given me such joy but as you will undoubtedly know it can also be frustrating and stressful as like you I have had some sleepless nights researching online and have to piece together bits from here and bits from there as there just does not seem to be enough clear and concise information out there, I fnd the best place to garnish good info is from the forums of people who are actually living this stuff but at the same time the forums can be tumultuous with ego's running rampant and end up reading stories for hours. Glad you got your battery wiring sorted, it can be dangerous with too small cabling going from things into batteries, I have had wires melt in front of my eyes as they were too small. Keep up the great work mate, can't wait to see more of your updates and projects.
